POTTSBORO — North Texas authorities seized 22 dogs found crammed inside a station wagon with their owner.

The owner locked the car doors and refused to come out when a constable tried to serve her a warrant for the seizure of the dogs early Monday, SPCA spokeswoman Maura Davies said.

Two puppies and 20 dogs were taken to a shelter, where they will remain until a judge decides who gets custody, the SPCA said. A hearing on the custody of the animals is set for Feb. 16 in Denison.

The dogs were in the car along with a pot of water, blankets and waste.

“The car was soaked with urine and covered in feces. The ammonia level in the vehicle was 23 parts per million even after the doors had been opened for several minutes. As a frame of reference, humans start experiencing health issues at 12 parts per million,” Courtney Stevens, SPCA of Texas rescue and investigations supervisor, said in a news release.

The owner does not face charges, Grayson County constable Michael Putman said. She was not coherent and the SPCA said it has contacted Adult Protective Services about the woman.
